thank you both tractorvet and Owen for your replies
Yes, it does have an electric fuel pump from the bowl to the carb. That functions just fine, I get a steady fuel flow.
The original time it quit, it had been firing just fine - right away with no choke. It began to develop a miss at high idle when I was mowing, and got worse and worse the next couple of times I tried to start it. (that was after the new coil, back in July) I then replaced the brass filter and the inline filter, pulled and cleaned the carb, and then discovered... after an $11 set of points and condenser, that it fired up. It just never started great after that, was very difficult. Can that leak where it seats to the manifold really cause all of this?
I know that I have a lot to learn yet, I haven't really been around these machines in 20 years, since my family had to sell the farm in 1987. Actually, we didn't have a gasser since 1982 or 83, when they bought the 484 diesel to replace the 444. even Dad is having trouble remembering what things they did to keep her running. Unfortunately for the timing, my timing light is too short to reach the battery and around to the timing marks, not to mention the Tach cable is broken, so I don't know the RPM's for sure anyway. Slowly, I can put money into it - and fix the next thing. =)
If they gave me the wrong coil (since it was bad when they sold me the tractor, it was free) this one needs external resistance, and the old one was too worn out to even read the numbers or words on it - could it have run flawlessly for maybe 20 hours, then within a few more hours of operation started operating really weak?
as for where the soleniod is suppoed to be, there was just a screw in the hole... nothing like an adjusting screw, just a short one set in to plug the hole. Thanks, Brian
